Oak saplings are obtained by planting an acorn in a plant pot filled with soil, then by using a watering can on the plant pot. A player must then wait several minutes in order for an Oak seedling to sprout into a sapling in the plant pot. (The seed can grow if you have it in your bank)

A player must have at least level 15 Farming to be able to make this item.

Planting the sapling in a tree patch with a spade in your inventory will result in the chance of growing an Oak tree. Players can ask the gardener for assistance in watching over their Oak tree for a payment of a basket of five tomatoes.
